Strabismus News and Research

Strabismus is a term used to describe eyes that are not straight and parallel. One eye may look straight ahead, while the other turns inward, outward, upward or downward. Strabismus is a serious eye condition that requires early medical treatment if it is to be successfully corrected.

Although one of the most serious consequences of the Zika virus (ZIKV) in infants is microcephaly, there is a broad collection of anomalies now known as congenital Zika syndrome (CZS). Some of the most serious are ophthalmologic, including macular scarring, retinal defects, low visual acuity, strabismus, and nystagmus.

Our group describes a new entity, which we refer to as “Developmental Split-Brain syndrome” which we discovered affected four individuals from three unrelated families. All affected individuals showed disruption of communicating tracts between the right and left side of the brain which meant that there is lack of coordination and communication between the two sides of the brain.

In a study published in Nature Genetics, Dr Saumya Jamuar, co-founder of Global Gene Corp and a visiting scientist at Harvard Medical School, under the supervision of Prof Christopher Walsh and A/Prof Timothy Yu of Harvard Medical School, reports on a new disease entity that they discovered in their quest to map novel human disorders related to brain development.

Scientists at the Institute for Infectious Diseases, University of Bern have developed an in vitro stem cell-based bioassay grown on multi-electrode arrays capable of detecting the biological activity of Clostridium botulinum neurotoxins.

A mini-symposium published in the Journal of the American Association for Pediatric Ophthalmology and Strabismus provides important insights into new techniques and treatments that show promise for eliminating retinopathy of prematurity (ROP) throughout the world.

Children are less likely to be diagnosed with crossed eyes, a condition known as strabismus, if they live in poor communities, according to an analysis led by researchers at the University of Michigan's Kellogg Eye Center.

Because of the beneficial effect of corticosteroids on lung function, especially in infants who are ventilator dependent, corticosteroids are, at times, administered to very low birth weight neonates to treat established or evolving lung disease. However, it has long been suspected that steroids may have negative neurodevelopmental effects on very premature infants.

Children with vision problems not correctable with glasses or contact lenses may be twice as likely to have a diagnosis of attention deficit/hyperactivity disorder (ADHD), suggests a study in the May issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

The largest study of childhood eye diseases ever undertaken in the U.S. confirms that the incidence of childhood myopia among American children has more than doubled over the last 50 years. The findings echo a troubling trend among adults and children in Asia, where 90 percent or more of the population have been diagnosed with myopia, up from 10 to 20 percent 60 years ago.

Children with amblyopia, commonly known as "lazy eye," may have impaired ocular motor function. This can result in difficulties in activities for which sequential eye movements are important, such as reading.

Amblyopia, commonly known as "lazy-eye," has been classically treated by patching the strong eye to force the weaker eye to be used. However, the concept of binocular dysfunction, in which the brain suppresses the image from the weaker eye in favor of the stronger eye, has motivated new approaches to amblyopia treatment.

Schizophrenia is associated with structural and functional alterations of the visual system, including specific structural changes in the eye. Tracking such changes may provide new measures of risk for, and progression of the disease, according to a literature review published online in the journal Schizophrenia Research: Cognition, authored by researchers at New York Eye and Ear Infirmary of Mount Sinai and Rutgers University.

When newborn babies open their eyes for the first time, they already possess nerve cells specialized in particular stimuli in the visual cortex of their brains - but these nerve cells are not systematically linked with each other.

Extremely poor vision can be caused by strabismus in early childhood or by a displaced optical axis. Amblyopia is caused not by organic damage to the eyes but by the brain incorrectly fitting together the images the eyes provide.

STReM stands for Super Time-Resolved Microscopy, and as STORM, PALM, and other methods are designed to improve spatial resolution of optical microscopy, we desire to improve the time resolution. STReM makes use of point spread function engineering to encode fast events into each camera frame.
